SHOK-BUFF Recoil System. This high performance recoil system is manufactured from the finest components to provide the absolute last word in quality and is an instant accuracy/reliability tune-up. If you demand the very best, insist on the original SHOK-BUFF Recoil System. The SKOK-BUFF Recoil System is a great value for the improved performance it gives your 1911 style Auto. The full length guide rod controls the recoil spring to keep it from kinking, which means smoother, more reliable functioning and longer spring life. The original SHOK-BUFF recoil absorbing, poly fiber buffers prevent the slide from pounding the frame, giving longer gun life and softer recoil. The combined effect of the match grade Wilson springs together with the smooth functioning full length guide rod, facilitates a more consistent barrel lock up, resulting in improved accuracy. Available for both Commander and Government/1911 GI models, the original WILSON COMBAT Recoil System is competition proven and the choice of champions! NOTE: We recommend using our #22 or #22P Barrel Bushing Wrench with this product.

"I ordered this set so I could experiment with different recoil spring tensions as well as install a new full-length guiderod. I found out it does not fit my MAC 1911 Commander and the rod will require milling to correct this issue. The included springs and buffers I have installed, however, and find they fit nicely."
